Is the Canon RF 100-300 2.8 Worth the Money?????

Today I travel to Darlington Indiana to capture some images at sunrise and share my opinions on the recently announced Canon RF 100-300 F2.8. I share images from a trip to Cades Cove from 0ver 10 years ago that I took with the Nikon D3 and the Sigma 120-300 F2.8. Do you have $9500 to spend on a new lens or are images from an older lens good enough??
